Just plug it in:
c & d = c² + d² - 4
2 & 1 = 1² + 2² - 4
= 1 + 4 - 4 = 1
Answer:
Step-by-step explanation:
Connect points I and K, K and M, M and I.
1. Find the area of triangles IJK, KLM and MNI:
2. Note that
3. The area of hexagon IJKLMN is the sum of the area of all triangles:
Another way to solve is to find the area of triangle KIM be Heorn's fomula, where all sides KI, KM and IM can be calculated using cosine theorem.

Bc 32 minus 34 is -2 then just add the 8
Answer:
The perpendicular bisector of BC
Step-by-step explanation:
